This invention relates to a door mounting for house cars, and concerns itself with a structure whereby the door is supported directly upon the side sill which is the most rigid member on the car. Due to the rigid character of the side sill, there is very little possibility of the door sagging or of any irregularities occurring in the door support. Further the utilization of the side sill will greatly reduce the cost in that the usual door track and its attaching brackets and the labor of securing the same in place are eliminated.

The invention comprises the novel structure and combinations of parts hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing which illustrates a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the diiferent views:

Figure 1 is a fragmentary side elevational View of a car having a door which is supported according to this invention.

Figure 2 is an enlarged sectional view taken through the upper part of the door illustrating 25 the side plate and the manner of guiding the door.

Figure 3 is an enlarged sectional view taken upon the line III-III of Figure 1.

Figure 4 is an enlarged sectional View taken 80 upon the line IV-IV of Figure 1.

Figure 5 is a fragmentary sectional view illustrating the mounting of the door upon its upper end.

According to this invention, the side sill 1 of the car is attached to the floor 2 so that it will project a sufcient distance beyond the end of the oor to provide a track for supporting the door for traveling movements. The door 3 is provided with a plurality of rollers 4 which are journalled upon stub shafts 5 which in turn are secured in suitable housing members 6 secured to the lower margin of the door. These housing members are provided with suitable depending portions 7 which cooperate with suitable guides 8 secured to the sill 1 for guiding the lower margin of the door in a substantially rectilinear line. The upper end of the door is provided with a projecting Z bar 9 which travels in a guideway formed by the outer flange l0 of the Z bar 11 commonly called the side plate, and an angle member 12 which is secured to the web 0f the side plate 11. The door is further guided at its lower margin by a guide plate 13 which is secured to the lower margin of the door between the two roller housings. It will be evident that (Cl. 21E-22) the door may be easily removed by removing certain ofthe intermediate guide brackets 8 and pulling the lower margin of the door outwardly. Consequently the replacement of an old door by a new one is a very simple matter.

1n addition to the advantages already set forth, an important advantage of the present invention resides in the fact that the railroad car may be made wider. The width of the car may be increased and the front door post provided with an inwardly offset portion and the rear door post set inwardly beyond the side of the car as shown in Figure Li. The panel rearwardly of the door must also be set inwardly as shown in Figure 4 so that the inset door will have room to slide.

The construction for the door will however be the same, in both instances, namely where the car is the usual width and when the car is of a greater width. In both cases, the door and the panel over which it slides must be inset so that the door will be supported upon the upper ange of thel sill which should not project beyond the main plane of the side of the car.

The door may also be suspended from its upper end in the manner shown in Figure 5. In this modified form the side plate 11 which as before related is in the form of a Z bar has its depending flange 10 turned inwardly as indicated at 14 to provide a track upon which rollers 15 secured upon the upper margin of the door may roll. In this modified form, the door is preferably provided with a deformed angle bar 16 which is attached at one fiange to the door with its outstanding ange bent upwardly to overlap the depending flange 10 of the Z bar 11 for guiding and maintaining ie door in proper relation to the track 14.

It will be noted that in both of the structures illustrated, the door is water proof at its upper edge. In the first case the Z bar 11 completely sheds the rain and water with respect to the door` In the second case the water is shed by the same Z bar with the exception that a certain amount may find its Way within the guideway formed by the member 15 from which it can readily escape at one end.

We are aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and We therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.

We claim as our invention:

l. In a house car having a side sill projecting beyond the edge of the floor thereof, and a sliding door having rollers mounted directly upon the projecting portion of said sill and cooperating means between said door and sill for guiding and maintaining the door upon said sill.

2. In a house car having a oor, a side sill secured to the bottom of said floor and having an integral portion projecting beyond the edge thereof to provide a track, and a door having rolling means supported upon said track.

3. In a house car having a floor, a side sill having an attaching flange secured to the bottom of the floor, said flange projecting outwardly beyond the edge of the floor to form a track, a door having rolling means supported upon said track and guide brackets on said sill for guiding said door in its movements.

4. In a house car having a side sill and a side plate provided with a pendant ange, said car having an inset doorway and an inset panel exposing a portion of said side sill, a door having rollers mounted `upon said sill, means on said side plate forming a guideway with said pendant flange and means on said door extending into said guideway.

5. In a house car having a, side plate with a pendant flange, means attached to said side plate and cooperating with said flange to form a guide- Way, a door for said ear, means for supporting said door Within said pendant ange and inwardly of the side of the car and a guide member on said door extending into said guideway.

6. In a house car having a side sill and an inset doorway, an inset panel rearwardly of the doorway exposing a portion of said side sill, and a door having rollers mounted upon the exposed portion of said side sill.

7. In a house car having a side sill and door posts inwardly offset from the side of the car, an inset panel adjacent one of said posts, said inset posts and panel exposing a portion of said side sill, and a door having rollers mounted upon the exposed portion of said side sill.
